  Fibre Channel (FC) link exceptions in Huawei OceanStor Dorado 18000 systems are addressed in the *HCIP- Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)*: "Common causes of FC link exceptions include mismatched port rates between the host and switch, poorly connected or faulty optical fibers, and mismatched optical module rates between host and storage front-end ports." Let's evaluate:

  Option A: Correct. Mismatched FC port rates between the host and switch cause link failures.

  Option B: Correct. Faulty or loose optical fibers disrupt FC connectivity.

  Option C: Correct. Mismatched optical module rates between host and storage ports lead to link exceptions.

  Option D: Incorrect. IP address settings are relevant to iSCSI, not FC, which uses physical connections.

• Question 92:

  An engineer manages a multi-tenant Huawei storage system. Which statement about tenant isolation is true?

  A. Block resources are isolated, but file resources are shared by all tenants.
  B. Tenants cannot have independent namespaces.
  C. Tenants can manage their own quotas and users if permissions are granted.
  D. All tenants must use the same access keys for object service.
  C. Tenants can manage their own quotas and users if permissions are granted.

  ---

  Explanation

  Tenants can manage internal users, quotas, and access policies when delegated permissions are enabled. File and block resources are isolated per tenant.

• Question 93:

  FILL IN THE BLANK The OceanStor Pacific series storage systems support the _______ feature. This feature uses the classic token bucket algorithm to control the traffic upper limit. If local tokens are insufficient, tokens are continuously generated and added to the token bucket based on the OPS and bandwidth upper limit of the corresponding QoS control object as the rate.

  Traffic shaping

  Explanation:

  This question pertains to Quality of Service (QoS) features in Huawei OceanStor Pacific series storage systems. The *HCIP-Storage V5.5 Training Material (Module 3: Scale-Out Storage Technologies)* describes: "The OceanStor Pacific series supports the traffic shaping feature, which uses the classic token bucket algorithm to control the upper limit of traffic. When tokens in the bucket are insufficient, the system generates and adds tokens based on the operations per second (OPS) and bandwidth limits

  defined for the QoS control object." Traffic shaping regulates data flow to prevent network congestion and ensure fair resource allocation, making it the correct feature name for this description.

• Question 94:

  When deploying a Huawei converged storage system, engineer A uses the UltraPath software. Which of the following statements are false about the load balancing algorithms of UltraPath?

  A. The min-queue-depth algorithm refers to the minimum queue depth algorithm. UltraPath is configured with this algorithm by default.
  B. Round robin is a min-task algorithm and can be used in scenarios where service I/O model data blocks delivered by the host are large.
  C. The min-task algorithm is a round robin algorithm and can be used in scenarios where the service I/O models delivered by the host have little difference.
  D. The algorithms fall into three types: min-queue-depth, round-robin, and min-task.
  B. Round robin is a min-task algorithm and can be used in scenarios where service I/O model data blocks delivered by the host are large.
  C. The min-task algorithm is a round robin algorithm and can be used in scenarios where the service I/O models delivered by the host have little difference.

  ---

  Option A is correct because UltraPath indeed uses the min-queue-depth algorithm as its default load-balancing method. This algorithm selects the path with the smallest queue depth, ensuring efficient path utilization.

  Option D is also correct because UltraPath provides exactly three load-balancing algorithms: min-queue-depth, round-robin, and min-task.

  Option B is incorrect because round robin is not a min-task algorithm. Round robin simply distributes I/O requests evenly across paths without considering task depth or queue load. It is not specifically designed for scenarios where large data blocks are delivered by the host. It is more suitable when I/O sizes are relatively consistent. Option C is incorrect because the min-task algorithm is not a round-robin algorithm. Min-task dynamically selects the path with the fewest outstanding tasks, while round robin is a

  static rotation mechanism that does not consider current load. Therefore, describing min-task as round robin and associating it with similar I/O models is inaccurate.

• Question 95:

  An enterprise customer has purchased a Huawei OceanStor Pacific scale-out storage system for service configuration. An engineer wants to deploy the NFS file sharing service on the storage system and configure the HyperReplicatlon feature. Which of the following configuration operations are correct?

  A. When configuring HyperReplication, the engineer needs to configure the replication network route information on the primary storage system. The replication network route does not need to be configured on the secondary storage system.
  B. To use the NFSv4.0 protocol for share access, the engineer can run the "change service nfs_config nfsv40_status=enable account_name=?" command to enable the NFSv4.0 service.
  C. After a converged storage pool is created, the engineer needs to enable the file service. The HDFS or object service does not have to be enabled.
  D. When configuring HyperReplication, the engineer needs to create a remote replication pair on both the primary and secondary storage systems and then add a remote device.
  C. After a converged storage pool is created, the engineer needs to enable the file service. The HDFS or object service does not have to be enabled.
  D. When configuring HyperReplication, the engineer needs to create a remote replication pair on both the primary and secondary storage systems and then add a remote device.

• Question 96:

  In a flash storage system, the ports of the cascading interface module or onboard cascading ports on the controller enclosure can only connect to port PI on the disk enclosure.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 97:

  For Huawei OceanProtect backup storage, which statement is true about deduplication domains?

  A. Each storage pool supports only one deduplication domain.
  B. Deduplication domains allow independent deduplication ratios for different workloads.
  C. Deduplication domains cannot be modified after creation.
  D. Deduplication must be disabled when compression is enabled.
  B. Deduplication domains allow independent deduplication ratios for different workloads.

  ---

  Deduplication domains isolate datasets to improve deduplication efficiency for different workloads. They can coexist with compression.

• Question 98:

  A bank customer purchases several Huawei flash storage devices to store upper-layer Oracle database service data. If an Oracle database fault occurs, engineers need to collect Oracle alert log files to locate the fault. Which of the following commands cannot be used to query the alert log path?

  A. ioscan -funC disk > /home/pvlinks_disk
  B. CRS_HOME/bin/diagcollection.sh
  C. show parameter background_dump_dest
  D. db2support outpath -d db_name -c
  D. db2support outpath -d db_name -c

  ---

  The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* addresses Oracle database troubleshooting: "To locate Oracle alert log files, commands like `show parameter background_dump_dest' (SQL*Plus) and `CRS_HOME/bin/diagcollection.sh' (Oracle Grid Infrastructure) can query or collect log paths. The `ioscan -funC disk' command (HP-UX) lists disk devices, which may indirectly help identify storage paths." However, "db2support outpath -d db_name c" is specific to IBM DB2 databases, not Oracle, making it irrelevant for querying Oracle alert log paths. Thus, option D cannot be used.

• Question 99:

  During a failure diagnosis of OceanStor Dorado, engineers use CLI commands to check disk status. Which statement is true?

  A. "show disk general" provides disk health, temperature, and running status.
  B. "show disk domain" displays SSD wear indicators only.
  C. "show disk smart" is used exclusively for NVMe disks.
  D. Disk status can be viewed only through DeviceManager, not CLI.
  A. "show disk general" provides disk health, temperature, and running status.

  ---

  "show disk general" displays comprehensive disk information including health and temperature. Other statements are incorrect.

• Question 100:

  An Internet customer has deployed a remote replication environment based on multiple flash storage devices. During actual service running, the customer discovers that there are multiple running statuses for a remote replication pair. Which of the following statements is true about the running status of a pair?

  A. After a pair is disconnected, if the pair is deleted from the primary or secondary site, which causes configuration inconsistency between the primary and secondary sites, the pair running status changes to "To be recovered."
  B. When the pair running status is "Split," the pair relationship between the primary and secondary LUNs is interrupted (not manually).
  C. When the pair running status is "Normal," data synchronization between the primary and secondary LUNs is complete.
  D. When the pair running status is "To be synchronized," the pair relationship between the primary and secondary LUNs must be manually disconnected to meet the service requirements of a single LUN.
  C. When the pair running status is "Normal," data synchronization between the primary and secondary LUNs is complete.

  ---

  The question focuses on the running statuses of remote replication pairs in Huawei's flash storage systems, such as OceanStor Dorado. The *HCIP-Storage V5.5 Training Material (Module 4: Storage Design and Implementation)* details the remote replication feature and its statuses. The material states: "When the pair running status is `Normal,' the remote replication pair is fully synchronized, meaning data between the primary and secondary LUNs is consistent, and synchronization is complete." This

  matches option C.

  Option A: Incorrect. The training material indicates that if a pair is deleted from one site, causing inconsistency, the status may not necessarily change to "To be recovered." Instead, it may require manual intervention or reconfiguration, and "To be recovered" is typically associated with link failures or incomplete synchronization, not deletion. Option B: Incorrect. The "Split" status occurs when the pair relationship is interrupted, but it can be due to manual intervention or automatic triggers (e.g., link failure). The

  parenthetical "not manually" is misleading, as the material does not restrict "Split" to non-manual causes. Option D: Incorrect. The "To be synchronized" status indicates that the pair is preparing for synchronization but is not yet consistent. There is no requirement to manually disconnect the pair for single LUN service needs, as the system can operate with the primary LUN independently during this state.
